types of angles and how to measure and draw angles

1. MATHEMATICS
CLASS 5
Geometry

2. WE WOULD LEARN ABOUT
Basic symbols in geometry
How are angles formed?
Types of angles
Measuring and drawing angles
using protractor

3. The branch of mathematics that is concerned with the
properties and relationships of:
point, lines, angles, curves, surfaces, and
solids
-
The visual study of shapes, sizes, patterns, and
position

5.  Has no beginning or end.
 Continues indefinitely in both directions.
 Can be illustrated by drawing arrows at each end.

6.  Has a beginning point and an end point.
 Line segments on a shape are called sides.
 Can be found in many shapes.

7.  Has a beginning point, but no end point.

8.  Lines in the same
plane that do not
intersect or cross
each other.

9. Two or more lines that meet
at a point.
Perpendicular lines form a right
or 90 degree angle
.

10. 
Made up of two rays with the same
start point.

The start point is called the vertex.

The two rays are called the sides of
the angle/arms of angles.
ANGLES

12.  A Protractor.

13.  Zero Angles
 Right Angles
 Acute Angles
 Obtuse Angles
 Straight Angles
 Supplementary Angles
 Complimentary Angles

14.  Are Parallel and equal 180 degrees.

15.  Two rays that create a 90 degree angle.

16.  Two rays that have a smaller angle than a
right angle.
 Degrees<90

17. Angles larger than a right angle and smaller than
180
( two right angles)but greater than (>90)
Degrees

18.  Angles equal to two right angles.

25. LET US REVISE HOW TO MEASURE AN
ANGLE
